Abstract

The concentration of sulphonate and or polycarboxylate compounds in an aqueous solution is determined by adjusting the pH of a portion of the aqueous solution to less than 3.0 when measuring sulphonate concentration or to between 3.0 and 12.0 when measuring polycarboxylate concentration; adding an effective amount of an aqueous solution of a metachromatic dye to the pH-adjusted portion; measuring the absorbency of the resulting admixture at a wavelength between 300 nm and 700 nm; and comparing this absorbency with absorbencies of standard samples containing known concentrations of polycarboxylate compounds and or sulphonate compounds, thereby determining the desired sulphonate and/or polycarboxylate concentration.
